It seems to have detected all 4. But I do see a MAC address not valid: ? ? (scrolled up)
EAL: PCI device 0000:04:10.1 on NUMA socket 0 ? EAL: probe driver: 8086:10ed rte_ixgbevf_pmd ? EAL: PCI memory mapped at 0x7fd39743e000 ? EAL: PCI memory mapped at 0x7fd39743a000 ? PMD: The MAC address is not valid. ? The most likely cause of this error is that the VM host ? has not assigned a valid MAC address to this VF device. ? Please consult the DPDK Release Notes (FAQ section) for ? a possible solution to this problem. ? EAL: PCI device 0000:04:10.2 on NUMA socket 0 ? EAL: probe driver: 8086:10ed rte_ixgbevf_pmd ?
